Hi,
quick question: what do RBG color values actually represent in darktable
just after basecurve module? For simplicity, let us assume "input color
profile" is standard color matrix with Rect2020-RGB as working profile
(In case that this is of any relevance.).
Backgroud of my question: The hazeremoval module (implicitly) assumes
that numerical RGB values are proportional to physical intensityies,
i.e., RGB values are from a linear color space. I was not aware of the
distinction between linear RGB and gamma-corrected RGB values, when I
implemented the hazeremoval module. Possibly, a gamma correction should
be taken into account in the hazeremoval module to reduce color artifacts.
